Watch the Nissan-sponsored DeltaWing get unceremoniously flipped by a Porsche during a race warm-up.

During testing yesterday for Saturday's Petit Le Mans at the Road Atlanta racetrack, a Porsche 911 GT3 flipped the Deltawing prototype race car off the track. Thankfully, Deltawing driver Gunnar Jeanette suffered no injuries, and according to Highcroft Racing, the car—which is running unclassified—will be on the track again today for practice.

Based on on-board footage of the crash, seen below, Jeanette begins to pass the Green Hornet Racing Porsche 911 GT3, driven by Peter LeSaffre, entering turn 11. It appears that LeSaffre tracks wide coming out of the chicane, which he admits in an interview with SPEED. Then, perhaps because of a loss of grip or some lift-off oversteer, LeSaffre breaks his racing line and makes contact with Jeanette, flipping him off the track and into the wall. In a release issued by Highcroft, the impact registered 7 Gs on the DeltaWing's telemetry. Ouch.

So far in its short racing career, the Batmobile-like DeltaWing just seems to be at the wrong place at the wrong time. At this year's 24 Hours of Le Mans, an accident with a Toyota put the experimental car out of the race. A second incident brings up more concerns about the DeltaWing, particularly its visibility. The low-profile body and matte black paint certainly make the Nissan-sponsored car look radical, but isn't helping it pop out in the mirrors of other drivers.

In the time that the 'Wing has managed to compete on the racetrack, its performance speaks for itself: At yesterday's Petit Le Mans testing, the DeltaWing had just set the session's fastest lap time before it wrecked. Ultimately, the car's best time was only 0.4 seconds slower than the fastest LMP2 car.

Still, the car has yet to finish a race. And as such, its two biggest advantages over standard Le Mans prototypes, lower fuel and tire consumption, have yet to be fully tested in a complete long-distance race.

Maybe the only thing the DeltaWing needs to succeed is a day-glo yellow paint job.
